Atwood Lab Write-up

Purpose : Find relationship between mass & acceleration and force & acceleration

Materials: Carts, Pulley, Weights, Washers

(insert a labeled drawing or picture)

Data:

a. force & acceleration

Total mass of cart + extra mass + 10 washers = _g= = kg
Average Weight of one washer =_ N (weight of 10 washers/10)

Trial	Number of washers	Total Fg from washers = mass *gravity (Newtons)	Distance (meters)	Time (sec)	Acceleration (a = 2d/t^2) (m/sec^2)

b. mass & acceleration

Total Fg ( washer mass x 9.81 N/kg)= ___ (should only use 1-3 washers)

Trial	Mass of Cart (kg)		Distance (meter)	Time (sec)	Acceleration (a = 2d/t^2) (m/sec^2)

Graph:

a. Mass vs. Acceleration

b. Force vs. Acceleration

Calculations: Show work

1. Weight of one washer = Weight of 10 washers / 10

2. Force of gravity: Force (gravity) = mass x gravity Gravity = 9.81 N/kg

3. Acceleration = 2 distance / time ^2
